DUST-MOP HEAD.

Specification of Letters Patent.

Patented June 20, 1916.

To all zu/0m t may concern:

Be it known that I, CHARLES A. CHAN- NELL, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements inl Dust-Mop Heads; and I do hereby declare that the following'is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to dust mop heads, and has for its object to provide certain improvements in that type of mop head disclosed in an application for Letters Patent filed by me Apr. 9, 1913, Serial No. 759,875, said improvements consisting, first, in novel features in the socket member for receiving the handle of the mop, and secondly, in means for tightening and retaining the rod or wire which holds the mop to the mop head.

The invention (in a preferred form) is illustrated in the drawings, and hereinafter more fully described.

In the drawings: Figure 1 is a top plan View of the mop head, showing the mop in dotted lines. Fig. 2 is a central section taken therethrough on line 2-2 of Fig. 1, and showing the handle attached. Fig. 3 is a fragmentary detail View in top elevation showing the locking and retaining elements in release position. Fig. 4 is a fragmentary view showing the gL p in the retaining ange of the mop hea-d for the reception of a locking member. Fig. 5 is a. fragmentary view shown partly in section illustrating the projecting members which engage the mop fabric. Fig. 6 is an edge view of one end of the mop head ange, terminating at the gap. Fig. 7 is a section taken on line 7-7 of Fig. 2. Fig. 8 is a front elevation of the locking member adapted to extend across the gap in the retaining flange of the mop head.

As shown in the drawings: The mop head;4V

comprises a sheet of metal bent to afford a bottom or base 1, and a grooved flange 2, which extends almost completely 'around said bottom, the ends terminating at a short distance from one another, to afford a gap for the reception of the attaching or locking member 3. T he attaching and locking member 3, comprises a strip of metal provided with a relatively narrow offset end 4, adapted to be inserted through the aperture 5, in one of the ends of the grooved flange 2, and having its opposite end 6, bent to conform to the curvature of the flange and of' a length to permity the same to be swung over the adjacent end of said flange and to be iirmly en* gaged against the inner face of the same.

The mop comprises a plurality of fabric strands 7, which are looped over at their middle and secured within a fabric covering band 8, thus affording an annular recess 9, through which is inserted a resilient steel wire or rod 10. Said wire 10, is hooked over at each of its ends 11, and 12, respectively, the end 12, adapted to extend through the aperture 13, in one of the ends of the iiange,

and the end 11, through one of the apertures 14, in said locking member 3.

The bottom portion 1, of the mop head is struck upwardly to afford slightly raised side walls 15, and as shown in Fig. 7, the walls thus formed are slotted or apertured to receive the integral downwardly extending and laterally turned ears of the cover plate 17 of the handle socket, to hold the same in register over the upwardly struck portion of the bottom 1. Said cover plate as shown, comprises a plate of metal which is stamped or struck to afford a curved portion, and downwardly depending lianges 18, which are so formed that when the plate is secured to the bottom 1, by means of the ears 16, as has been described, said curved portion will extend obliquely upward from the bottom plate, as shown in Figs.. 1 and 2. Apertures or slots 19, are provided in said cover plate at a point intermediate the curved portion and the depending iianges 18, and as shown in Figs. 1, 2 and 7, a plate 20, is rigidly secured in position beneath the curved portion of the cover plate 17 by means of integral ears 21, on the same which extend through the apertures or slots 19, and secure said members in rigid relation to receive a handle 22, therein. The bottom portion 1, of the mop head isapertured or cut away for the sake of lightness.

As shown in Figs. 5 and 6, the flange 2, is struck outwardly ata plurality of places to adord pointed members 24, adapted to engage the fabric of the mop when the Same is secured in positicm.v

The operation is'as follows: kWhen it is desired to ysecure the mop upon the mop head, the wire or rod 10, is threaded through Y'the'recess 9, in the mop, and the band 8,

of the mop is clamped into the groove of the flange 2, and engaged at the sharp points 24, by means of the wire 10, with the end 12,

thereof engaged in the aperture 13, ink one end of said flange 2, near the gap. The end Vl1, of the wire is then engaged in one of the apertures lll, in the locking member 3, as shown in Fig.-3. The member 3, is then turned on the oset end Ll, engaged in apw about the fulcrum point, will draw 'the end l1 of the wire circumferentially and inwardly thus tightening the Wire around the flange 2, to effectually secure the mop thereon. One

of the members 17 and 20, affording the ven'- gaging means for the handle 22, is stamped to afford threads whereby said handle may be threaded therein.V When it is desired to clean the mop the free end of the locking member 3, is raised upwardly and permitted to swing outwardly, thereby releasing end 11, of said wire 10, and permitting the mop to be detached from the grooved flange wall 2, and the mop may then be washed and cleaned or replaced by a new one, as desired. Y y

I am aware that details of construction may be varied through a wide range without departing from the principles of this invention, and I thereforev do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim asmy invention: f

1. In a device of the class described, a mop head comprising a base platea socket cover plate comprising a curved portion provided with integral depending flanges, adapted to be secured to said base plate with the curved portion arranged obliquely with respect to said base plate, and a complementally curved'platesecured to said cover plate to Yafford a recess adapted to receive a Vmop handle intermediate the same and the curved portion'of the cover plate.

2. In a device of the class described, a mop head havinga portion thereof struck upwardly, a socket cover plate therefor comprising a curved portion provided with depending flanges adapted to be secured to the base plate and in a position above'the upwardly struck portion of the same, and a complementally curved .plate secured to said cover plate at points intermediate the curved portion of said cover plate and depending n flanges thereof.

3. In a device of the class described, a mop head comprising a base plate, a'cover plate comprising a curved portion provided with integral depending flanges, adapted to be secured to said base plate, and a com pleinentally curved plate secured to said cover plate toalford a recess adapted toreceive a mop` handle intermediate the same and the curved portion of ,the cover plate.

In testimony whereof I have hereunto subscribed my name in the presence oftwo subscribing witnesses. l y
